end ot the member 18 being slightly below the plane of the upper surfaceof the horn, as shown in'Fig. The work positioning member 18 is aflexible flat strip of metal troduction oi the shoe parts having at itsupper end, arms which embrace the upper end of the horn, a pin andslotcon-- nection 24 between the upper end 26 oi the member 18 and theupper end of the horn being provided to limit movement of the upper end26 away from the horn. Prefer ably the upper end of the horn is recessedat each side as indicated at 28, so that the slotted arms 30 play in therecesses, thus avoiding projections on the sides oi the horn whichn'iightprove objectionable by engaging with thelining oi? the shoe. Thehorn illustrated in the, drawings is of a wellknown type like thatdisclosed in the said patent to Goddu and in an earlier patent to thesame inventor No, 265,227, granted Sept. 26, 1882,:3I1Clfl'16nl3l0116din the specification of the later patent. Thishorn 1 is arranged to bedepressed by a treadle (not shown) in order that the work may be readilyintroduced and removed from the machine. The construction in the citedpatents to G'oddu such that the horn may be rotated so that it'asteningsmay be inserted in all parts of a shoe bottom, as, tor instance, insecuring an outersele to a shoe. In heel seat nailing the horn isdifnarily secured against rotation and this is .f? in the illustrativeconstruction in order that Q work positioning member l8 maybe retainedin position to press the shoe against the gage 16. The work itself isshifted laterallyduring feeding and fastening inserting operations, thehorn being fixed against lateral movement. Preferably the worksupporting surface of the horn is pro vided with a clinching cavity 32located in the line of fastening insertion and operative to insureproper clinching of the fastenings as each is driven into and throughthe work by the driver 8.

In nailing the heel seat end of the sole in place, the shoe isintroduced over the upper ends of the horn and the work positioningmember 18, the resiliency in the spring member 18 being such thattheupper end 26 0t I the member may be pressed into contact with the hornto providea spacebetween said up per end 26 and the work gage for thein- Normally there is a considerable space between the upper end of thehorn and the work gage so that the shoe may be readily placed inposition on the horn and freely turned to present different portionsthereof for the insertin oi :tastenings. The member 18 is so arranged asto project into this s1 ace and from one standpoint may be said to takeup self-adjustingly the proper portion of this space, thereby causingthe shoe parts to be definitely positioned between the combined horn andwork positioning member on one side and the work gage on the other side.It will be obvious, therefore, that the work positioning member 18 willconstantly press the shoe yieldingly against the work gage l6 and thusensure that the fastenings will be driven at proper distances from theedge or the sole. This positionin of the fastenings is secured throughthe co-operation oi the work positioning member 18 and the work gage l6,the latter being arranged to engage the counter portion ot the shoeupper, this co-operation resulting in inserting a linc'of fasteningswhich follows the contour of the counter portion of the upper and, threfore, at a uniform distance from the edge of the sole. The iastenin sthus driven are properly p05 ned, due to the con inuous operation of thework positioning 1: nber it is to be understood that applica ntsinvention is not to be limited to specific embodiment herein shown anddescribed, as various modifications may be made by those skilled in the'art Without departing from the scope of the invention as set forth inthe appended claims. v
